The invention discloses a power supply switch control circuit with the power down delay function. The circuit is particularly adaptive to constant powered and MCU circuits. On the condition of omitting a special power supply chip, the power down delay function of the entire circuit can be realized simply. The circuit is simple in structure and is divided into two portions, namely an input level conversion portion and a power supply switching circuit portion.
